Behavioral Interviewing

While there are a number of definitions, for our purposes, soft skills are all of the skills that are not technical. Meaning - the you that shows up the interview, as well as your technical ability. Your interview is composed of your technical prowess, as well as your soft-skills and ability to answer non-technical questions around teamwork, leadership, failure (yes), ability to adapt, timeliness, and communication skills.

If you have heard of the airport test - when hiring managers ask themselves would I want to be stuck in an airport with this person? - your non-technical stories will help them answer that question. In short: non-technical questions will ask you to tell a number of stories that supplement your technical mastery.

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

• There are always 24 hours in a day.
• February is always 28 days long.
• Any 24-hour period will always begin and end in the same day (or week, or month).

Python

This is my recommended Python setup, as of Fall 2022. The Python landscape can be a confusing mess of overlapping tools that sometimes don't work well together. This is an effort to standardize our approach and environments.

Tools and helpful links:

• Python docs: https://docs.python.org/3/
• Python Standard Library: https://docs.python.org/3/library/index.html - Start here when you're trying to solve a specific problem
• pip: https://pip.pypa.io/en/stable/ - Python's standard package installer, included with the language itself
• pipx: https://pipxproject.github.io/pipx/ - Global script installer, built on top of pip
